One of the things I've come to realize anyone can do to make a better world is to not support monopolies and duopolies.

Don't use Google to search, use duckduckgo.

Don't use Facebook, use Nostr.

Don't vote Democrat or Republican, vote Libertarian or a write in candidate.

Don't buy the big brand in the store, buy the little guy brand.

Go for the fringe group as that pulls power from the monopoly or duopoly.

It isn't convenient, but it's free market supporting

And it's something feasible that everyone can do
